Looks like you've done your research on this.
I pretty much agree, but wonder why you've selected the Futura 144 over say the GO 144 (same shape, different/more robust construction).
At your weight (90 Kg./198 lbs.) a little more volume (GO/Futura 155) might be helpful.
To get from where you are (skill level) to fully planing, hooked in and in the footstraps, there are going to be a few "trips over the front/catapaults" and the heavier but more robust TufSkin construction might serve you well.
As far as comparisons with other boards, the Futura/GO range are indeed very easy to sail and should help you to progress as quickly as possilbe.
Hope this helps,
